In case of earache, headache and sore throat, acute otitis media, acute pharyngitis and acute tonsillitis caused by upper respiratory tract infection are usually considered. It may be related to bacterial infection or mycoplasma infection, or viral infection. If the condition is serious, a blood test should be done to see if the white blood cells are high and the monocytes are high. If the white blood cells are high, it is considered to be caused by a bacterial infection and requires antibiotics. If you are not allergic, you can take amoxicillin, azithromycin, roxithromycin. If it is caused by viral infection, take antiviral drugs, such as pandanus, pandanus root, and diarrhea relief pellets. If you have a headache, you can have a head CT, and if there is no major problem, it is usually an upper respiratory tract infection as well. Upper respiratory tract infections last about a week, and if treated promptly, they will heal in a week or so.
